Abstract
The utility model relates to a delayed coking high temperature oil-gas closing valve, comprising valve body, valve seat, flashboard, valve rod, valve cover, support, transmission mechanism, sealing member and installation part. Blow off valve is arranged at the bottom of valve cover and valve body; valve cover and valve body are sealed by stuffing box; cooling fins are arranged on valve cover outside the stuffing box in order to improve cooling speed and seal ability of stuffing box. It has advantages of good seal ability and safe reliable use.
Description
Technical field
The utility model relates to a kind of valve, particularly about a kind of high temperature isolating valve.
Background technique
The high temperature isolating valve generally adopts the Wedge gate valve structure, by valve body, valve seat, flashboard, valve rod, valve gap, support, driving mechanism and Sealing and assembling set, two blow down valves are set on valve gap, the valve body lower curtate is provided with a blow down valve, be used for cleaning the solid particle of valve inner, adopt packing box seal between valve gap and the valve rod, major defect is that leak easily at the stuffing box position valve uses a period of time in the high-temperature oil gas medium after, and poor sealing performance also produces potential safety hazard.
Summary of the invention
The purpose of this utility model is the shortcoming that exists at prior art, and a kind of good seal performance, delayed coking high-temperature oil gas isolating valve safe in utilization are provided.
The technological scheme that realizes the utility model purpose comprises valve body, valve seat, flashboard, valve rod, valve gap, support, driving mechanism and Sealing and assembling set, on valve gap, blow down valve is set respectively with the valve body lower curtate, adopting packing box seal between valve gap and the valve rod, mainly is to be provided with radiating fin on the valve gap in the stuffing box outside.
The advantage that the utility model is compared with existing product is on the valve gap in the stuffing box outside radiating fin to be set, and increases the radiating and cooling speed of stuffing box, and the sealability and the product usage safety performance of stuffing box is provided.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Now further describe the technical solution of the utility model in conjunction with the accompanying drawings and embodiments.
Delayed coking high-temperature oil gas isolating valve as shown in Figure 1, comprise valve body 1, valve seat 2, flashboard 3, valve rod 4, valve gap 5, support 6, driving mechanism 7 and Sealing and assembling set, two blow down valves 13 are set on valve gap 5,14, valve body 1 lower curtate is provided with a blow down valve 8, after valve installs, open the blow down valve 13 on the valve gap 5 earlier, 14 and the blow down valve 8 of valve body lower curtate, from blow down valve 13, feed high pressure water or steam in 14, make ducted solid particle, iron is cut, welding slags etc. are discharged from the blow down valve 8 of valve body 1 lower curtate, the shut-down purge valve 13 then, 14,8, the valve input is normally used.Adopt stuffing box 9 sealings between valve gap 5 and the valve rod 4, stuffing box 9 is installed by packing seal pad 10 and Gland 11, is provided with radiating fin 12 on the valve gap 5 in stuffing box 9 outsides, and radiating fin 12 is provided with some, evenly is arranged on the valve gap 5.
